This invention relates to bottle filling devices of the type in which the bottle, through the medium of a filler head, is connected with ia vacuum pump and a source of liquid thg ottle, liquid flows in to supply its place. It is important that such heads'should be so constructed that the may be easily cleaned and of a materia substantially inert in contact with any one of a large range of liquids. v Y

My object therefore is to devise such a head and to arrange the apparatus so that a number of heads may be readily served from one vacuum air line.

I attain my object b forming the heads of wood and the tubing 0 glass, connections and stuffing boxes being of elastic rubber.

air' line connected to each head is placed a liquid trap and a spring controlled valve adapted to open to limitthe vacuum in the line to any desired sub-atmospheric pressure.

The whole is constructed in 'detail substantially as hereinafter described and as illustrated in the accompanying drawings in which v Fig. 1 is a side elevation, partly in section of the apparatus; and

Fig. 2 a rear elevation of the head.

In the drawings like numerals of reference indicate corresponding parts in the dilferent figures.

1 is a table or bench, to which is secured a standard 2, preferably formed of pipe, to.

which the filler head is secured. Preferably the standard extends laterally and then downwardly and the head is secured thereto by means of the threaded nipple 3'threaded into a metal plate secured to the upper block 4 of the filler head. I

The filler head comprises the up er block 4 and the lower block 5'. These b ocks are preferably formed of wood, which is inert in contact with any one of a large range of liquids. Each block has a cavity formed ,therein.. The upper block 4 has an opening 6 in one side opening into the interior space. Into this opening extends a pipe 7, prefer ably of glass. Surrounding this pipe is an annular elastic gasket 8. which is preferably fitted into a recess in the side of the head.

surrounding the opening 6. A clamp plate 9 engages the gasket, which clamp plate may y so that, as the air isremoved from' In the the parts as hereinbefore referred to.

be set up to compress the gasket by means of the bolts 10 passin through the clamp plate 5 and the block 4, t us forming a fluid tight 'oint between the gasket, the pipe and the lock. A pipe 11 1s connectedin the same manner to the block 5 in communication with the space therein by means of a similar gasket 12, the clamp plate13 and bolts 14.

In the underside of the block 4 is formed an opening 15 communicating with the space in the block. In the block 5 are formed the openings 16 in alinement with one another and the opening 15. A glass tube 17 passes through the openings-15 and 16. Surrounding the tube, between the two blocks, is located an elastic gasket 18, preferably having its ends set in recesses surrounding the adjacent openings 15 and 16. It is evident that, when this elastic gasket is compressed, by drawing together the blocks 4 and 5, a fluid tight joint will be formed between the gasket, the tube and the blocks. Surrounding the glass tube 17 is a larger glass tube 19 extending into the lower opening 16 of the block 5. Surrounding this-tube and fitted into a recess about the lower opening 16 is an elastic gasket 20. Engaging the gasket is a clamp plate 21, which is adapted to be set upby bolts-22 passing through the clamp plate and through the two blocks 4 and 5. By tightening up these bolts, the gaskets 18 and 20 are compressed to form fluid tight joints betwegn T e glass tube 17 is used as a liquid tube and extends a. short distance below the lower end of the glass tube 19, through which the air from the bottle is withdrawn Fitted over the part of the tube 19 projecting below the clamp plate 21 is an elastic cushion 23, against which the mouth of the bottle may be compressed to secure a fluid tight joint.

Preferably the various elastic'gaskets and the cushion are formed of high grade rubber.

The pipe 7 is the liquid supply pipe and dips into the liquid reservoir 24, which may be located in any convenient position.

The pipe 11 is the air pipe and is connected with the airline 25, which is connected with an air pump, not shown.

In the air pipe is located a trap 26 of ordinary construction adapted to trap any liquid accidently drawn up-through the air pipe if 6 a bottle be filled too full. There is also 10- cated in the air pipe a relief valve 27 adapted to admit atmospheric air into the air pipe if the vacuum increases above a pre-determined maximum.

While any adjustable relief valve would serve my purpose, I show a valve having a valve bonnet 28 formed with an inwardl facing valve seat 29 at its lower end. Wit

- the valve seat co-operates the valve disk 30 formed on the valve stem 31, which extendsup through the bonnet and has a. nut 32 threaded on its upper end. Between this nut and the upper end of the bonnet is located a coil spring 33. Openings 34 in the side of the met form inlets through which .air may pass and thence down around the valve stem and past the valve whenever the vacuum in the pipe 11 is sufliciently high to open the valve against the tension of the spring 33. By adjusting the nut I can ensure that the vacuum at no time becomes suflicient-l great to cause foaming of the liquid enterin the bottle, hence, though a number of difl erent heads are actuated from the one air line, each ma be adjusted to suit its own requirements.

Iii general the mode of operation is the same as in all vacuum filler heads, the bottle being held in osition against the cushion 23' until the air t erein has been sucked out and re lac odby the liquid flowing through the tn 1 What I claim is:

1. A filler head for bottle filling apparatus comprising two blocks aligned with one another, each having a space for fluid formed therein, aligned openings communicating with such spaces being formed in two sides of one'block and the ad acent side of the other; a pipe for fluid connected with each block and communicating with the space therein; a fluid tube extending through the openings and space of one block and into the interior space of the other-through the openin therein; an annular elastic gasket fitted between the blocks and through which the tube passes; means for clamping the blocks to com ress gasket to form a fluid tight oint between the gasket and the tube and the blocks; and a tube connected with the second opening of the first mentioned block surrounding the first mentioned tube, one of the tubes being longer than the other.
